Inaccuracies in workpiece location lead to errors in position and orientation of machined features on the workpiece, and strongly affect the assemblability and the final quality of the product. The ac....
In process of vehicle crash simulation analysis, pre-processing takes about 40%~60% of the work time. Shortening period of data preparation of crash simulation is an efficient way to speed up CAE anal....
The paper presents the results of finite element study conducted by developing a three dimensional model of single cylinder engine piston assembly. A new method to estimate the piston assembly frictio....
An investigation was performed on steering tie rod for cracking with strength and buckling analysis theory, which showed a low risk of failure. In order to solve this problem, a “necking down” method ....
Achieving and sustaining high levels of quality is an essential prerequisite for successful and sustainable development. The requirement for the description of the existing quality levels are measurem....
In finite element analysis, mesh density is a critical issue which closely relates to the accuracy of the finite element models while directly determines their complexity level. This paper presents a ....
In today's light-weight vehicles, the strength of spot welds plays an important role in overall product integrity, reliability and customer satisfaction. Naturally, there is a need for a quick and rel....
Vibration testing is carried out as part of the sign-off procedure for vehicle body and power unit mounted components to ensure that the components can survive their working life without damage. The p....
The automotive lighting industry continues to optimize the balance between heat performance and cost performance for exterior lighting components. Headlamp bezel applications, in particular, must meet....
Continuously variable transmission (CVT) offers many advantages to vehicle performance over traditional transmission technologies. A novel cam based CVT was proposed in US patent # 4,603,240, by J. Kl....
Frames are important structures found in many transportation applications such as automotive bodies and train cars. They are also widely employed in buildings, bridges, and other load bearing designs.....
Recently the automotive industry has focused on reducing product development time to correspond with the customer's demands. Especially when quickly changed. The decreased product development time sho....
Bonded piston seals (BPSs) which consist of metal ring and rubber lips are used as hydraulic pistons for Automatic Transmission (AT) or Continuously Variable Transmission (CVT). While engaging clutche....
A turbulent CFD simulation based on the Large Eddy Simulation approach (LES) is under development at Autodesk. The code is being designed to provide designers with rapid estimates of drag coefficient ....
Truck chassis assembly forms the structural backbone of a heavy commercial vehicle. The main function of the truck chassis is to support the aggregate components and payload acting on it during operat....
A predictive model of a specific vehicle was modeled in the system-level physical modeling tool, MapleSim, for performance and fuel consumption prediction of a full vehicle powertrain, driving a multi....
